What to Compare Before Buying
- Brightness: The stated maximum output is 200 lumens. Compare that with the visibility level you want for your usual rides.
- Modes: Five lighting modes are listed. Check that the mix of steady and flashing settings matches how you plan to use the light.
- Mounting: Saddle and seat post mounting are stated. Confirm that your bike has the space and seat post type needed for the included bracket.
- Power and charging: The built-in 1200 mAh battery is USB rechargeable. Check whether that charging method suits your routine.
- Fit: The seat post bracket is stated to suit round and aero seat posts. Confirm that this matches your bike before ordering.
How It Works
The light is set up as a rear bike light with selectable lighting modes. Brake sensing increases the brightness for 3 seconds when deceleration is detected, and the auto on/off function is described as turning the light off after 30 seconds of inactivity before waking it again when movement is detected.
The button and indicator light also show battery and charging status, which gives a quick check on power level during use and charging.
Before You Decide
Confirm that you want the brake sensing and auto on/off functions, then check the 200 lumen output, five mode set and USB rechargeable battery against your riding needs. Also make sure the saddle or seat post mounting arrangement suits your bike, including the round or aero seat post bracket detail if that matters for fit.
Position and Check Before Riding
When choosing between saddle and seat post mounting, consider which position leaves the rear light unobstructed from behind, including with any rack or luggage fitted. Before setting off, check that the light is visible and illuminated; do not rely on brake sensing or auto on/off as a substitute for that check.
